I'll start a work on merging the documentation to the Guidelines
(volunteers are welcome :-)). You can just change the content and remove
the part which differs from Fedora, but try to keep changes as smallest
as possible to allow easy merging of changes between Fedora and SUSE. I'm
planning to use a git repository to help track a changes between Fedora
and SUSE, but it will be a lot of manual work (I expect).

I hope you have the git repo available. It would be easier for some of
us to assist.

Yes, I'm working on this. But without api.php on SUSE wiki I have to yet
another script for our wiki, because I cannot use some mediawiki library (as I
use for Fedora wiki). And my current script has a bug, because he downloads
only a first warning from every page :).
